To all whom it may concern:

Be it known that I, ALFRED NAGELBER a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented an Improvement in Railroad Construction, of which the following is a specification.

This invention relates to railroad construction and more particularly to the road bed and the manner in which thesleepers or ties are laid and connected therein in order to adequately secure and support the rails. The object of my invention is to prevent the deflection of the track due to the settling of the ground or other causes and to distribute uniformly the concentrated loads upon the rails; to prevent the bunching of the ties in case of derailment; to eliminate the possibility of the spreading of the tracks and to decrease the wear of the ends of the rails at the joints thereof where the parts of adjacent rails are connected by the fish plates; to prevent the creeping of the rails and also to make the track a homogeneous structure.

In carrying out my invention I preferto employ for each rail a series of tie-plates secured to alternate sleepers-withbrace bars extending between adjacent tie-plates to space the same and beneath the intermediate sleepers to assist in spacing and supporting the rail, also a complementary series of tie plates and brace bars extending between the intermediate sleepers or cross-ties and beneath the intervening sleepers, each tie-plate being so constructed as to be suitably secured to its sleeper as well as with means for engaging the flange of the rail to secure the same in position, all of which will-be hereinafter more particularly described.

In the drawing:

Figure l is a plan of a short section of railway made in accordance with my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a plan of one of the tie-plates showing the brace bars extending therefrom and the means for gripping the flanges of a rail, and

Fig. 4 is a cross section showing thev manner in which the flanges of the rail are secured in and to the tie-plates, Figs. 3 and 4 being made on an enlarged scale.

Referring to the drawing in carrying out this invention I employ a series of tie-plates indicated at 10 and adapted to be placed on and secured to alternate sleepers or cross tiesellr, I also employ a second series of tie-plates indicated at 12., These areadapted in a similar manner to beplaced on and secured to the intermediate sleepers, or crossties 13. The tie-plates 10 are connectedby bra'cecbars 14 extending, between each pair of tie-plates and beneath the intermediate sleeper 13 so as to 'space the alternate sleepers 11 and to assist in spacing and sup: porting the intermediate sleeper 13. Similarly, each pair of tie-plates 12 is connected by a brace bar 15 which extends'betweenthe intermediate sleepers. 13 to which the pairs of tie-plates 12 are secured, spacing these sleepers 13 andassisting in spacing and supporting the intervening sleeper 11.. 1

As shown in Figs. 3 and 4: each tie-plate may be generallyrectangular in plan and provided atoneLend with a bolt or spike hole 16 ,and at the opposite end with a bolt or spike holes 17 by means of which and suitable ,boltsor spikes the. tie-plates may be secured to the upper surface of a sleeper orcross-tie. Aslis also shownin these figures of the drawing, one endof the tie-plate preferably adj acent' the corners thereof may be provided withlugs 18 to engage one flange ofa rail while adjacent the opposite end of thetie-plate the same maybe pro vided with a clip member l9having holes 20 therein adapted to receive bolts 21 which alsopass through bolt holes provided therefor in the tie-plate so that the clip member -maybe adjusted to position against the fiangeon the other side of the rail and the bolts tightened to secure the rail 22 in posis tion against the tie-plate.

From the foregoing description it will be apparent that the track made in accordance with my invention is a homogeneous structure and as each sleeper or cross-tie is connected to its ad acent sleepers or cross-ties the deflection of the track is decreased if through the sinking of the road bed or other causes there is any tendencv to deflection. The brace bars also act to space the sleepers andprevent the bunching thereof in cases of derailment. The tie-plates with their connected brace bars also strengthen each other so as to eliminate the tendency of the tracks to spread and as the parts are hom0- geneously connected the ends of the rails cannot be" raised or lowered, relative to one another and hence this construction also reduties the wear on the joints at the ends of each. rail section.

I claim as my invention:

1. In a railway road bed construction and in combination with the sleepers employed therein, a series of tie-plates each secured to a predetermined sleeper, a second series 7 of tie-plates each secured to another sleeper, and devices for connecting adjacent tieplates in each series thereof to. space the sleepers to which they are secured and to assist in supporting an intervening sleeper.

2. In a railway road bed construction and in combination with the sleepers employed therein, a series of tie-plates each secured to alternate sleepers, a second series of tieplates each secured to an intermediate sleeper, devices connecting the adjacent tieplates of the first aforesaid series thereof for spacing the sleepers to which they are connected and assisting in spacing and supporting an intervening sleeper, and devices complementary to the aforesaid clevices for connecting adjacent tie-plates of the second series thereof and assisting in spacing and supportinga sleeper to which a tie-plate of the first aforesaid series thereof is secured.

3; In a railway road bed construction and in combination with the sleepers employed therein, a series of tie-plates secured to alternate sleepers, a series of tie-plates secured to intermediate sleepers, brace bars connecting the tie-plates on alternate sleepers and extending under the intermediate sleepers, and brace bars connecting the tieplates on intermediate sleepers and extending under the intervening sleepers.

4. In a railway road bed construction and in combination with the sleepers employed therein, a series of tie-plates secured to alternate sleepers, a series of tie-plates secured to intermediate sleepers, brace bars Copies of this patent may be obtained for connecting the tie-plates on alternate sleepers and extending under the intermediate sleepers, brace bars connecting the tieplates on. intermediate sleepers and extending under the intervening sleepers, and means for securing a rail to the said tie,- plates.

- 5. In a railway road bed construction and in combination with the sleepers employed therein, a series of tie-plates secured to alternate sleepers, a series of tie-plates secured to intermediate sleepers, brace bars connecting the tie-plates on alternate sleepers and extending under the intermediate sleepers, brace bars connecting the tieplates on intermediate sleepers and extend ing under the intervening sleepers, lugs at one end of each of the said tie-plates, and means adjacent the other end of each tieplate for securing a rail in position therein in conjunction with the said lugs.

6. In a railway road bed construction and in combination with the sleepers employed therein, a series of tie-plates secured toalternate sleepers, a series of tie-plates secured to intermediate sleepers, brace bars connecting the tie-plates on alternate sleepers and extending under the intermediate sleepers, brace bars connecting the tie-plates on intermediate sleepers and extending under the intervening sleepers, lugs on one end of each of the said tie-plates for engaging one flange of a rail, a clip member adjacent the opposite end of each tie-plate, and means for securing the clip member to the tieplate and the other flange of a rail to coact with the said lugs for securing the rail in position on the tie-plate.

ALFRED NAGELBERG.
